Celine Dion is showing off her sexy 44-year-old body in the pages of V Magazine.

The singer, who is strutting her stuff at her Florida home without a top, told the mag:

"I was scared a little bit because this is so different for me, but I'm glad I did it. Usually there's always a reason when I do a photo shoot, there's not the opportunity to go crazy."

Dion, who has sold more than 200 million albums worldwide, also opens up about hubby Rene Angelil's cancer ordeal. She adds:

"I've been an open book all my life and I think that's why people like me," she said. "For me to tell someone that my husband had cancer, that we were struggling to have kids, or whatever we've gone through, talking about my life lets people know the real me."
